Description

Technical Field

[0001] The invention relates to the technical field of antistatic plates, and in particular to a production equipment system for antistatic plates. Background Art

[0002] Gypsum, whose main component is calcium sulfate, includes natural gypsum and industrial by-product gypsum. Industrial by-product gypsum is a by-product of some industrial processes, which mainly includes phosphogypsum and desulfurized gypsum. At present, the cumulative stockpile of industrial by-product gypsum has exceeded 550 million tons, of which more than 50 million tons of desulfurized gypsum and more than 500 million tons of phosphogypsum. The large-scale stockpile of industrial by-product gypsum not only occupies land, but also wastes resources. The acid and other harmful substances contained in it are easy to pollute the surrounding environment, which has become an important factor restricting the sustainable development of flue gas desulfurization and phosphate fertilizer enterprises in my country. According to statistics, in 2009, the amount of industrial by-product gypsum produced in my country was about 118 million tons, and the comprehensive utilization rate was only 38%. Among them, about 43 million tons of desulfurized gypsum, with a comprehensive utilization rate of about 56%; about 50 million tons of phosphogypsum, with a comprehensive utilization rate of about 20%; therefore, the development of secondary utilization technology of industrial by-product gypsum is still a topic worth studying at present. my country uses natural gypsum to make calcium sulfate boards. However, 70% of natural gypsum mines are mined underground. Therefore, completely solving the pollution problems of phosphogypsum and desulfurized gypsum will be beneficial to the country and local governments in energy conservation and emission reduction, environmental protection, and can promote the sustainable development of surrounding compound fertilizer companies.

The batching screw 2 and the gypsum storage bin 11, the silicate cement storage bin 12 and the filler storage bin 13 are flange-connected. The wet material bin 32 is connected to the high-speed beating mixer through a pipeline. The dry powder bin 31 and the wet material bin 32 are welded on the operating platform, and pneumatic valves are used. A second pressure gauge weighing sensor is provided in the dry powder bin 31, and a third pressure gauge weighing sensor is provided in the wet material bin 32. The dry powder bin 31 and the wet material bin 32 both use pneumatic valves to control the discharge;

[0033] The mixing unit includes a dosing machine 41, a mixing mixer 42 and a dosing cup 43. The dry powder bin 31 and the wet material bin 32 are respectively connected to the mixing mixer 42 through a DN200 hose. The dosing cup 43 is driven forward and backward by a cylinder. The dosing cup 43 is connected to the dosing machine 41 by bolts. The mixing mixer 42 is connected to the dosing machine 41 by welding through an iron plate slide. The mixing mixer 42 uses a pneumatic valve to control the discharge of materials.

[0034] The molding unit includes a manipulator 52, a hydraulic press 51 and a return water mixing tank 53. The manipulator 52 and the hydraulic press 51 are independently installed on the horizontal ground. The center of the discharge port of the hydraulic press 51 corresponds to the center of the quantitative cup 43. The material grabbing center of the manipulator 52 corresponds to the center of the discharge port of the hydraulic press 51. The hydraulic press 51 and the manipulator 52 are connected by a photoelectric switch for signal transmission. The water generated by the hydraulic press 51 during production flows through the ditch to the return water mixing tank 53. The water in the return water mixing tank 53 is pumped to the high-speed pulping mixer through a DN63 pipeline for recycling.

[0035] The control unit includes a human-machine interface and a PLC control cabinet. The human-machine interface is located on the operating platform. The human-machine interface is connected to the PLC control cabinet for communication. Various parameters are input manually. It can run automatically and manually, and can be remotely controlled and monitored in real time to achieve fully automated production.

[0036] The specific production process is as follows:

[0037] S1. 70% (weight percentage, the same below) of the material in the gypsum storage bin 11 is sent into the dry powder bin 31 by the batching screw 2. After reaching the first-level weight setting, the conveying is stopped; 5% of the material in the silicate cement storage bin 12 is sent into the dry powder bin 31 by the batching screw 2. After reaching the second-level weight setting, the conveying is stopped; 5% of the material in the filler storage bin 13 is sent into the dry powder bin 31 by the batching screw 2. After reaching the third-level weight setting, the conveying is stopped; after the metering is completed, the mixer on the dry powder bin 31 is automatically started, and the stirring is stopped after 3 minutes; wherein the gypsum is one or more of phosphogypsum and desulfurized gypsum, and the filler is slag powder or fly ash;

[0038] S2, 8% fiber, 60% tap water, 0.1% water reducing agent, 0.1% defoaming agent, 0.3% cellulose ether, 0.1% starch ether, 0.3% retarder, 0.3% rubber powder, 0.5% silicone waterproofing agent and 0.2% antioxidant are added to the high-speed beating mixer in sequence, mixed at high speed for 15 minutes, and then stirred slowly in the secondary mixing bin of the high-speed beating mixer, and then the materials are sent to the wet material bin 32 by a slurry pump. When the set weight is reached, the pumping is stopped;

[0039] S3, the mixer 42 starts to start, and after a start delay of 10s, the pneumatic valve of the wet material bin 32 is automatically opened, and the materials therein flow into the mixer 42. After the wet material bin 32 is completely discharged, the valve is closed to carry out the next working measurement; then the valve of the dry powder bin 31 is opened, and the materials therein flow into the mixer 42. After the dry powder bin 31 is completely discharged, the valve is closed to carry out the next working measurement; after the mixer 42 stirs for 3min, the pneumatic discharge valve is opened, and the mixed materials enter the dosing machine 41 for slow stirring. After the mixed materials are completely discharged, the valve is closed to carry out the next working measurement;

[0040] S4, slide out the mold frame of the hydraulic press 51, and send the quantitative volume of material into the mold frame through the quantitative cup 43 by the cylinder. The mold frame slides into the hydraulic press 51 and performs high-pressure pressing for 45 seconds. The mold adopts upper and lower water filtering devices, the upper mold adopts vacuum water extraction, and the lower mold adopts self-overflow, so that 50% of the water is pressed out by high pressure. After the pressing is completed, demoulding is performed, the slide table moves backward, and the formed plate is sent out;

[0041] S5. After the photoelectric switch of the robot 52 detects the plate, it automatically grabs the plate and stacks it on the pallet. The plate is manually forked into the transfer place by a forklift for hydration and drying.

[0042] Example 2

[0043] The difference between this embodiment and embodiment 1 is that, in this embodiment, Figure 2As shown, the hydraulic press 51 is provided with two discharge ports, each of which is provided with a corresponding quantitative cup 43. Accordingly, the number of manipulators 52 is set to two, the material grabbing center of one manipulator 52 corresponds to the center of one discharge port of the hydraulic press 51, and a photoelectric switch is used for signal transmission connection between the hydraulic press 51 and the corresponding manipulator 52.

[0044] In this embodiment, two production paths can be produced simultaneously, which improves production efficiency to a certain extent and also improves the single-machine utilization rate of the preceding equipment, which is beneficial to reducing production costs.

[0045] Example 3

[0046] The difference between this embodiment and embodiment 2 is that this embodiment is composed of two sets of production equipment systems for antistatic plates as in embodiment 2, such as Figure 3 As shown, the two systems share a silicate cement storage bin 12, a filler storage bin 13, a high-speed beating mixer and a return water stirring tank 53, thereby obtaining the production equipment system of the antistatic board in this embodiment. According to the usage requirements of gypsum storage bin 1170% (weight percentage, the same below), 5% of silicate cement storage bin 12 and 5% of filler storage bin 13, the design of two systems sharing a silicate cement storage bin 12 and a filler storage bin 13 is more reasonable, which can reduce the additional site space and storage bin cost required for the number of additional systems; the provision of a high-speed beating mixer and a return water stirring tank 53 also improves the utilization rate of the equipment, and can realize multi-line simultaneous production, with higher production efficiency, higher equipment integration, and more compact and reasonable structure.

[0047] Example 4

[0048] This embodiment compares the production equipment system of the anti-static plate provided in Embodiment 3 with manual production, and the comparison is shown in Table 1:

[0049] Table 1 Comparison between the production equipment system of the antistatic plate provided in Example 3 and manual production

[0050] name Degree of automation Labor intensity Number of people required 8 hours output Labor and energy costs Example 3 high Low 3 1500 pieces 1.5 / piece Artificial none high 12 1000 pieces 3.8 / piece

[0051] It can be seen from the above table that the production equipment system of the anti-static plate provided in Example 3 has the advantages of high degree of automation, low labor intensity, small number of production personnel, high production efficiency and low production cost compared with manual production.
